What is a Dental Implant?

Before we dive into the topic, let’s first understand what a dental implant is. An implant is a screw-like structure that is surgically placed in the upper or lower jawbone. It serves as an artificial root for a prosthetic tooth, also known as a crown, which replaces a missing tooth.

There are two primary methods of attaching a crown to an implant. The first method involves placing a crown on top of the implant and securing it with a screw. The second method involves cementing a titanium structure to the implant, onto which the crown is then glued.

Why Do Dental Crowns on Implants Loosen?

If you’re experiencing a loose crown on your dental implant, it’s essential to understand the potential causes. The most common cause is issues with occlusion, which refers to how the teeth come together when biting or chewing. Improper occlusion can put excessive pressure on the crown, leading to loosening.

In some cases, the implant itself may be the problem. It could be poorly integrated with the bone or incorrectly placed, causing movement and instability.

How to Determine the Cause of Loosening

To determine whether the crown or implant is the source of the problem, it’s important to observe the type of movement and any associated pain. If only the crown is moving and there is no discomfort, it is likely an issue with the crown. However, if a whole block of teeth moves, accompanied by pain, it may indicate a failing implant.

Common Causes of Dental Crown Loosening

  1. Occlusion: Incorrect bite alignment or prematurity can put undue stress on the crown, causing it to loosen.
  2. Overload: Excessive force from habits like bruxism (teeth grinding) can result in crown loosening.
  3. Missing Teeth: An uneven distribution of chewing forces due to missing adjacent teeth can lead to crown instability.
  4. Transmission Errors: Inaccurate information transmitted to the laboratory during crown fabrication can result in ill-fitting crowns that have a tendency to loosen.

Preventing and Addressing Crown Loosening

To prevent crown loosening, it’s crucial to ensure proper occlusion during placement. Regular check-ups are recommended to monitor the condition of the crown and the fit of the implant. Ideally, the crown should be screw-retained or cement-retained, allowing for easy adjustment and re-tightening if necessary.

If a crown does become loose, it is advisable to visit your dentist to diagnose the cause accurately. Depending on the issue, the crown may need to be repositioned or replaced.


While dental crown loosening on implants can be a frustrating issue, understanding the potential causes and taking preventive measures can help avoid complications. By maintaining good oral hygiene, regularly visiting your dentist, and addressing any issues promptly, you can enjoy the benefits of a stable and long-lasting dental implant.
